Perhaps you should try some spelling variations:
nano science » nato science, radio science, nanoscience _
2c physics » 2 physics, 2d physics, 22 physics
20 physics » 2 physics, 10 physics, 2d physics
series b » series 10, series 11, series 12
series 1 » series 3, series 2

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %nano science ((series b) OR (series 1))%3a%((2c physics) OR (20 physics))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%nano science ((series b) OR (series 1))%3a%((2c physics) or (20 physics))%22".
• Adding a wildcard symbol may retrieve word variants: %nano science ((series b) OR (series 1))%3a%((2c physics) or (20 physics))%22*.
